The kids
They had two small children and a baby to look after, and there was no babysitter in town that they knew of who could look after the kids. They tried finding someone who was going to do it but to no avail. In the end, they realised that they will have to take the kids with them that night.
This wasn’t a problem for Jackie or Adam of course, they loved their kids more than anything, they just wanted a night alone that’s all. But it wasn’t going to go their way this time and they were okay with that. They made plans for the whole family and waited for the night to come.
